A kind of electronic duster
Technical field
The utility model relates to the plant protection mechanism technical field, is a kind of electronic duster specifically.
Background technology
At present, powder injection process is a kind of method of preventing and treating of damage by disease and insect at crops such as greenhouse, booth, orchard and paddy rice commonly used, the large-scale powder spraying machine that the apparatus that dusts mainly is divided into hand duster and is driven by tractor.Hand duster realizes dusting operation by the hand control rocking bar, and labour intensity is bigger.The large-scale powder spraying machine is limited by then the region, can't be in the greenhouse, place operation such as booth, terraced fields.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic duster, and it uses the work of accumulator drive motors, replaces artificial rocking bar operation, and labour intensity is low, and is applied widely.
The technical solution of the utility model is as follows:
Be provided with accumulator and motor in electronic duster powder case, the motor upper end connects blower fan, and the coaxial connection of draught fan impeller is positioned at the dust feed device of powder bucket, and powder bucket bottom is provided with regulation and control powder door with the blower fan junction.The blower fan outlet connects the flexible pipe that joins with jet pipe, and the jet pipe other end connects dust nozzle.
The operation principle of electronic duster: the rotation of motor-driven draught fan impeller, the medicinal powder and the air that drive in the blower fan rotate together, and medicinal powder and air spray into flexible pipe after the pressurization of spiral space, after jet pipe sprays from dust nozzle.Meanwhile, the draught fan impeller of rotation drives dust feed device and stir medicinal powder in the powder bucket, and medicinal powder is constantly descended under the effect of gravity, falls into blower fan by regulation and control powder door.The amount of dusting of duster is by the gate control of regulation and control powder.
The electronic duster of the utility model is reasonable in design, and is simple to operate, uses light, cheap, widely applicable.
Description of drawings
Fig. 1 is the electronic duster structural representation of the utility model.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is described:
This electronic duster is made up of power switch 1, accumulator 2, draught fan impeller 3, regulation and control powder door 4, dust feed device 5, powder bucket 6, braces 7, powder case 8, case lid 9, dust nozzle 10, blower fan 11, jet pipe 12, flexible pipe 13 and motor 14.
Closure is positioned at the power switch 1 on powder case 8 sides, accumulator 2 is motor 14 power supplies, the impeller 3 that motor 14 drives in the blower fan 11 rotates, thereby the medicinal powder and the air that drive in the blower fan 11 rotate together, the outlet from blower fan 11 after the pressurization in the spiral space that blower fan 11 and impeller 3 are formed of medicinal powder and air sprays into flexible pipe 13, after jet pipe 12 is from dust nozzle 10 ejections.Motor 14 also drives dust feed device 5 when driving draught fan impeller 3 rotations and rotates in powder bucket 6, and the medicinal powder in the powder bucket 6 is stirred in the rotation of dust feed device 5, and it is constantly descended under the effect of gravity, falls in the blower fan 11 by the regulation and control powder door 4 of powder bucket 6 bottoms.When the different amount of dusting of needs, the slippage of aperture control medicinal powder that can be by regulating powder door 4, thus realize control to the amount of dusting.
When dusting operation, only need the medicinal powder that needs spray is installed in the powder bucket 6, closed case lid 9 is taken machine on one's body the back of the body with the braces 7 that is connected on the powder case 8 then, dust nozzle 10 is aimed at crop, turn on the power switch 1, medicinal powder will be sprayed onto on the crop, finish spraying operation, operate very simple, light.
